摘要: 本文综述了近30年来植物营养与作物抗旱性关系的研究进展,重点讨论了植物必需的营养元素氮、磷、钾等对作物抗旱性的影响,指出这些营养元素主要通过水分调节、渗透调节、气孔调节和光合调节等一系列生理生化机制来增强作物的代谢活性、提高作物抗旱性。并对今后这方面研究中的重点内容进行了评述。

Abstract: This paper briefly presents the progress of study on the relationship between plant nutrition and drought resistance of crops in recent 30 years, and emphatically discusses the effects of three necessary macro_nutrition ─ nitrogen, phosphorus and potassium on drought resistance in crops. The results show that through a series of biological and biochemical mechanisms such as, water regulation, osmotic regulation, stoma regulation, photosynthesis regulation and so on, these nutrition_elements can raise the activity of metabolism and also drought resistance of crops. Some important aspects concerning these issues are discussed.
